UNITED STAT S PATENT OFFICE HENRY SIDDALL, OF SAN FRANCISCO, CALIFORNIA.

IMPROVEMENT IN GP AlN-SEPARATORS.

Specification forming part of Letters Patent No. 37,362, dated January6, 1663.

To all whom it may concern."

Be it known that I, HENRY SIDDALL, of the city and county of SanFrancisco, in the State of California, have invented a new and usefulMachine for Separting and Cleaning Grain, entitled Siddalls BlastGraiuSepara- I tor and I do hereby declare that the following is a full,clear, and exact description of the construction and operation of thesame, reference being had to the accompanying drawings, making a part ofthisspecification, in whic Figure l is a perspective view with the sideshown open. Fig. 2 is a sectional view, representing the machine cutthrough the center vertically and lengthwise. Fig. 3 is a verticalsectional view of the spouts A, B B B, and G. t

To enable others skilled in the art to make and use my invention, I willproceed to describe its construction and operation.

Letter A represents the spout through which the grain passes into themachine, and is made elbow-shaped or angular, so that it may cause thegrain to scatter and thereby effect an equal division of the same intospouts B which spouts are for distributing the grain throughout thebreadth of spout G.

G is a spout through which the grain is introduced into the blast-spoutF, and is placed at the side of said blast-spout, for the purpose ofallowing the grain to fall from a given height and strike upon thebottom piece, D, thence bounding through opening E, and will therebyscatter throughout the whole area of. the blast-spout F.

F represents the blastspout in which the grain is cleaned by means of acurrent of air, which passes upward, carrying the refuse substancesthrough opening G. The grain finds egress at S.

H is a blast-chamber. The smallest end of the same is attached to theblast-spout F, and is constructed with a gradual increase to a largerdimension at the other end, thereby causing the current of air to bereduced hence all the grain that is carried up by said blast will dropinto chamber I, and the refuse matter, except such as dust and chaff,will fall into chambers L and 0.

I is a returning-chamber, situated under the blast-chamber H, for thepurpose of catching the grain that is carried up through the openin g G,from whence it is returned. By the use of this returning-chamber a muchstronger blast can be applied than otherwise.

L and O are chambers for catching the refuse matter. The heaviest of thesame will drop into L, the lighter portion into 0.

K is a spout for transmitting the return grain from chamber I to theelevator W and X, and it is optional whether the same empties into thehopper V or the elevator.

J and M are hinged pieces forming adjustable partitions between chambersI, L, and O.

R is a suction-fan for generating a current of air in the blast-spout F.

V, the hopper, holds the grain previous to its passing into the machine.U, the slidegate, regulates the flow of grain from hopper V.

W is an elevator, in which are placed pulleys 1 and 2 and belt Y, towhich are fastened cups X. The Whole of this apparatus is for carryingthe grain upward.

Z represents ,the slide for regulating the current of air.

The elevator W X and the fan B may be driven in any convenient manner.

I introduce the grainintohopper V, and the flow therefrom is regulatedby the slide-gate U, whence it is carried upward through elevator W bycups X, and is delivered into spout A, whereit'is equally divided byspouts B, and is distributed throughout the breadth of spout G, thencestriking upon the bottom piece, D, thence bounding through the openingE,and is thereby scattered throughout the whole area .of the blast-spoutF, and is fanned by a strong current of air or blast. The clean passesout at S, and may be gathered in any convenient manner. The refusesubstances are carried up through the opeuin g G into blast-chamber H.Here a portion of grain is also carried up, which drops into thereturning-chamber. I. A portion of the heaviest refuse matter willlikewise fall into said chamber I, and this I call the return grain,

which is transmitted through spout K back to the elevator, whence it iscarried up, thus passing through the machine again, at the same time andwith the regular supply of grain, thus keeping a part of the graincontinually returning. By this process I am enabled to effect a morethorough separation. The refuse substances are carried along theblast-chamber H, and the heaviest of the same will drop into chamber L,the lighter portion into 0. The dust and chaff is drawn into fan R, fromwhence it is blown into the open air. The refuse matter is extracted atthe slides P and N.

What T claim as my invention, and desire to secure by Letters Patent,is-- 1. Spout A, provided with distributingspouts B, as described.

2. Spouts A O, placed relatively to blastspout F, When constructed andoperating as described, and for the purpose set forth.

3. The arrangement of chamber 1, spout K, and elevator W X, for thepurpose of returning a part of the grain, as herein set forth anddescribed.

HENRY SIDDALL.
